As part of EBMUD’s infrastructure renewal program, the Acorn Reservoir located at the end of Eagle Ridge Drive in Blackhawk will be replaced. The existing 1.2-million gallon (MG) welded-steel reservoir is oversized for the community it serves and has reached the end of its useful life. EBMUD will build two smaller tanks with the combined capacity of 1 million gallons. Replacing one large tank with two will allow EBMUD to take one tank out of service during low-demand periods. This will reduce maintenance costs and improve water quality.
EBMUD will be postponing construction at Acorn Reservoir. The contractor has experienced construction delays and requested to terminate their contract due to financial hardship. At this time, the contractor is going to complete the first phase of the project which includes finishing the first tank, valves, and piping by July 2018. EBMUD plans to rebid the next and final phase of this project, the second tank, within the next 12 months to another contractor. No construction activity will take place during this time.
Once the contract is awarded, the final phase of the project will take approximately 12 months to build. Notifications will be sent to the neighborhood once construction schedules are finalized.
Construction for this project began in September 2015 and is expected to be completed by 2020. EBMUD will grade the area next to the existing reservoir, build a retaining wall and build one of the replacement reservoirs before removing the existing reservoir. Once the new reservoir is complete and in service, EBMUD will demolish the old reservoir and build the second reservoir in its place. During the first stage of this project residents can expect to hear and see hauling trucks and equipment required for grading. Allowable work hours for this project are Monday through Friday from 7 a.m. to 6 p.m.
